The single biggest driver in human evolution was the challenge of matching the demands and capacities of our out-sized brain against the relative limitations of a weak physique. When researching the ‘whims of mother nature’, nothing is arbitrary. Sure, there are variances and distributions, but you can be sure that somewhere in the mix resides an objective mean – defining form and substance with a purpose.

Hair, like skin, is part of our genetically malleable, adaptable, outer layer, protecting us from the elements, the heat, cold, wetness, dryness, and utilizing the visible and not-so-visible light (energy) spectrum. Early primates and proto-humans had straight hair, which was an asset in low exertion foraging environs of ranging temperature, but not conducive to extending our physical endurance in the competition for food and survival, especially in mid-day Africa. Tightly coiled, moisture resistant head-hair created an enhanced barrier to ultra-violet (UV) radiation by turning many times on itself. This configuration also allows the release of perspiration droplets into a more optimal evaporative state whereby the droplets capture the heat of air moving around the coils before the perspiration rolls off and evaporates said heat away from the body. Presto! Cool scalp, cool brain, and greater endurance.

Conversely, straight hair was a liability, as it is more moisture absorbent, becoming heavy and causing it to stick to adjacent hair shafts and the scalp, effectively blocking the airflow required for heat exchange and dissipation. The straight hair of those precursors to modern humans would have made them less able to exert themselves for survival and advancement.

So with all due respect to Chris Rock, there is no such thing as ‘good’ or ‘bad’ hair. Curly, kinky, or nappy hair adaptation meant survival and prosperity as a species, in the birthplace of humanity. Moreover, just as coiled hair and pigmented skin conveyed advantage in Africa, straight hair, and light skin adaptation did the same moving north, in logical ways and for discernable reasons (more on this later). And for the record, Don Imus (here) is a true moron. The Rutgers ladies (pictured) are infinitely more appealing than his sorry behind.

While asking the question ‘Why are White People White?’ (here), I touched on that black people are black by the same mechanism. However, my explanation was too brief, and the question deserves its own full answer. Keep in mind this evolutionary cheat-sheet: first, there was panting and hairiness, and then came limited sweating and hairiness, and now we have full-body sweating and no hair (little hair).

To begin, earlier hairy primates, or proto-humans, living in Africa were less efficient at dissipating the body heat that resulted from strenuous exertion (hunting, gathering, and avoiding predators). Panting is the way most mammals cool themselves, rather than through sweating. As an evolutionary alternative, sweat glands appeared first over hairy bodies and then over less-hairy bodies, allowing for rapid cooling and quick evaporation. Evaporative cooling pulls heat away, countering the insulating effect, whereby the moisture stays on the skin, trapped by hair, and increasing in temperature from both the sun and internal exertion.

Indeed, sweat glands were an improvement over panting, allowing for greater exertion, but there was another hurdle. Full-body hair on proto humans grew out of ‘white (non-pigmented) skin’ underneath, in combination to regulate Vitamin D(3) production, for bone and reproductive health. Without the hair to block the sun, the skin had to take on this critical task by itself, via melanin production, thereby making the evolutionary case from fully covered, dark haired, white-skinned, proto-humans into hair-less dark-skinned humanoid descendants. Viola, black people!

It was relentless large brain demands (thinking) of proto-humans that drove body evolution to change and advance. Hairlessness, sweat glands, and dark-skin proved a potent combination in response, allowing humans to run greater distances, fight longer fights, dehydrate at a slower pace, and recover normal body temperature more quickly. Humanoids quickly became formidable foes, as their body capabilities ‘caught up to’ their brainy demands.

Being black, I scarcely wondered why I was black, but I did often wonder why white people were white. I never believed in the ‘God wanted it that way’ answer. It seems very natural that whites and blacks would harbor the same question, however taboo it is to toss it into conversation. Indeed, science has provided us with an answer, but I hardly see it in print for non-scientists.

The scientific record shows relatively hair-less humans evolving from hairy primates in Africa. At the time when hairy proto-humans ‘loss’ their hair and developed sweat glands for cooling their big brains, they also needed to adapt their production and regulation of the pro-steroid hormone, Vitamin D(3), which was critical to healthy bones and reproduction. The result was an adaptive higher level of melanin in the skin, turning it dark. Viola, healthy dark-skin humans to populate the world!

As early Africans migrated north to Eurasia, with its lessened sun intensity, dark skin posed a problem. Vitamin D(3) fell to unhealthy levels, except that built-in genetically adaptive skin traits quickly kicked-in to lightened skin responsible for producing the required D(3). The farther north they ventured the lighter the skin needed to be to absorb the right amount of sun. It really is that simple. There is a great book that explains all of this in detail, written by recognized skin authority, Nina Jablonski PhD., called “Skin: A Natural History” (here).

So there it is - latitude (north/south position) on the globe pretty much dictates skin color (here). There are a few exceptions to this rule, associated with levels of Vitamin D in the diet. By example, the Inuits (indigenous Arctic people) are relatively darker, even at such a high latitude, because of oily-fish diets laden with Vitamin D(3). Aborigines in continental Australia, arriving via the ‘intercoastal migration’, maintained their melanin through similar fish-rich diets, on the coast, coupled with the fierce demands of an intense interior desert sun.

As a side bar, and from a Vitamin D(3) healthiness perspective, the continental US is (on average) too sunny for most fair whites, and not sunny enough for most brown-skin blacks. Everyone needs Vitamin D management for good health.

It took them long enough, but Google, who owns blog publishing service Blogger, finally canceled the hate-filled ranting at the blog, WhyBlacksSuck. blogspot.com. The blog owner (under INDRA MAGHAVAN) tried to say that his site was not a hate site, but from his name down to his postings the real story was the opposite. Over the past six months, the blogger had begun to run out of hate-gas, but the site needed a hard ending nonetheless. It was last cached on Dec. 14, 2010.

I complained to Blogger regularly, once I became familiar. I also realized that he was pointing his twisted brethren to this blog, perhaps because I ‘air out the laundry’, at times. To be clear, I respect and depend upon protected speech, via the First Amendment; however, if Google wants any resemblance of good citizenship they sure-as-hell had better bring their hammer down on people who use hate-speech to incite violence on others, regardless of their affinities.

I see plenty of blog owners who write just this side of the hate-line, claiming they are simply expressing their opinions. However, when you read the vitriol-laced carnage fantasies that makes it into the comments, you understand better the relationship between the spark and fire. Absolving one’s blogging-self of hate comments, moderated or not, under some twisted sense of the First Amendment is nothing but crap.

All groups have their burdens, and blogs are powerful vehicles for openness and honesty pertaining to such. However, Why Blacks Suck was just hate that earned its participants an over-due exit to the internet bottoms.

The New York Times has put up a map tool linked to US Census data, cutting across race, education, income, and housing. Interesting tool for setting a context for looking at where this country has been, is presently, and where it seems to be going. Check it out (here).

Some events simply demand that you stop, take notice, and give credit where it is due. The woman to the right side of the picture probably saved this police officer’s life (video). The officer’s roadside battle with his assailant was not going too well before the passing woman decided that he could ‘use a hand’.

The courageous Samaritan’s well-timed licks upside the old geezer’s head were just what the officer needed to regain control of the potential deadly situation. The woman said everybody else was just passing the fight by, but she couldn’t. Give that woman the key to Dayton, and a bravery commendation. She is a hero!

The most powerful control tool of a parent, teacher, employer, or government, is the willingness to encourage others to believe you can only tell them the truth, when, in fact, your charter compels you to lie. This is the conundrum the founding fathers were addressing when they wrote the first amendment to the US Constitution, regarding freedom of religion, press, and expression.

As children, we are taught to believe the words of the police, and other authority figures. However, police officers are trained to lie, as part of their job. Of course, there are specific instances where they may not lie, but those are exceptional. We are purposely misled into believing that they cannot lie, but that itself is a lie - perhaps it is the biggest of lies.

When you hear an authority append “in the interest of National Security” to something they are saying, it really means that the person is not telling you the truth, and/or is telling an outright lie, allegedly for your safety and well being, in someone’s authoritarian opinion. Presidents, senators, and congressman routinely lie, the least of which is about dalliances with interns. Governments lie to each other all the time, and in turn they must lie to their own people to protect these earlier lies – again, under the cloak of protecting national security.

The mechanism, in this country, which keeps the lies from completely spinning out of control, leading to chaos and anarchy, is freedom of the press. When people inside of government (typically) see the lies mounting to the point where they can no longer sleep or eat or look their families straight in the face, they have somewhere to go, to leak, where the truth can still mean something – the press.

Without the press, or the ability for all citizens to speak freely, all freedom is eventually lost. It is not that Wikileaks, or its founder, is perfect or always right; they are not. However, the protection afforded all of us by the Constitution is critically dependent upon the idea that those who lie, as a matter of course, do so with knowledge that their lies and impacts may ultimately come to light as such. Liars beware!

I have been to plenty of White funerals, but Black funerals are in a class of their own. You know something wild is going to happen – but like “Death at a Funeral” (2010), you don’t know what. The question today is why, during the ‘audience tribute’ portion of the service, somebody must always dig up an event about the deceased, or an audience member, that makes everyone squirm and try to hide inside their programs?

When Mr. or Ms. ’Bigmouth’ first approaches the microphone, you can hear knowing people mumble a desperate prayer of, “Oh Lord please…” Others look away hoping to become invisible, just like in school when the teacher wanted someone to lead the pledge of allegiance. Everyone knows that the pastor’s two-minute limit is useless to stop what is coming next.

The story told is usually something like, ‘so-and-so (the deceased) and I were out one Saturday night, you know, sowing some wild oats, when we met these ‘fine’ girls. After the po-lice showed up and they were going to arrest us except blah, blah, blah! Man, I am going to miss so-and-so, and don’t think he didn’t accept Christ as his savior, because I was right there when he did! And y’all know I don’t lie!"

Relief only comes when the last person has spoken. The minister gets things back on track by segueing any notion that the person was ‘saved’ into their passport through the ‘pearly gates’. On the positive side, you always come away knowing the deceased was a real person rather than just the sum of the one-sided good stuff people usually present. Everyone should attend at least one 'real' Black funeral.
